A friend of mine gave me a box of 168gr matchkings to load for him last night. He's shooting a 300win.

The problem is that I don't have a sierra manual. Does any one have a load they can share with me.

I have RL22, RL19, IMR4831 and 4350.

Thanks in advance.

About 73 grains of IMR4831 should work well. So will 70grns of 4350.

my 300 WM likes RL22..76gr. Fed 215M primers.
max load for RL22, for a 168gr. bullet is around 79.5...RL22, does really well in my rifle.
I have some data for IMR 4350 also. Have to look...sakofan...

RL-22 From 66.9 grains to 79.5 grains
Winchester WLR Primer

heres a new link I found, that has alot of loads.
